An insertion site for a cannula (23) on a skin (8) of a patient is prepared by applying a skin cover unit (1) of the type comprising a window (2) and a wall (3) in extension of the window (2) and connected to the window (2) by a bending region (4) for bending the wall (3) into an angled orientation relatively to the window (2); wherein the win-dow (2) comprises a stabilizing frame (5) and an ultrasonic-transparent flexible sheet (6) within the frame (5). The flexible sheet (6) is glued onto the skin (8) of the patient for ultrasonic investigation of the insertion site through the flexible sheet (6). By bending the bending region (4), the angular orientation of the wall (3) is adjusted into an approximately perpendicular orientation relatively to the window (2) for separating the insertion site from the flexible sheet (6) by the wall (3). The cover unit (1) in or at the bending region (4) comprises a stabilizer (9) that is configured for maintaining the angled orientation between the wall (3) and the window (2) by a stabilizing action of the stabilizer (9).

Herein is disclosed a composition for application to a wound comprising: a first layer comprising a skin adhesive, wherein the first layer has a wound-facing side and a non-wound-facing side and, in a first area, apertures extend through the first layer from the wound-facing side to the non-wound-facing side; and a second layer disposed on a non-wound-facing side of the first layer, the second layer comprising a polymeric film that is continuous in that it extends over and covers each of the apertures of the first layer, the second layer having a moisture vapour transmission rate (MVTR) of at least 500 g/m.sup.2/24 hours, measured in accordance with BS EN 13726-2:2002, wherein the composition further comprises a third layer disposed between the first layer and second layer, the third layer being a supporting layer for the first layer, the third layer having apertures therethrough, substantially corresponding to the apertures in the first layer. A method of making such a composition is also disclosed.

A system for treating a linear wound on a patient has a closing dressing bolster for placing on the patient's epidermis over the linear wound, a sealing subsystem for providing a seal over the closing dressing bolster and the patient, and a reduced-pressure subsystem for delivering reduced pressure to the sealing subsystem. The sealing subsystem and reduced pressure subsystem are operable to deliver reduced pressure to the closing dressing bolster. The closing dressing bolster is operable under reduced pressure to develop a inward closing. The closing dressing bolster may include one or more closing members on each side of a center wound area to create the inward closing when under reduced pressure. A compressive force may also be developed. Other systems and methods are presented.

A liquid indicating article is disclosed. It can have a single layer, but generally will have at least two layers bonded together, wherein a visible layer masks a second colored layer wherein the visible layer is a wicking material that becomes semitransparent when wet, wherein the colored layer is a permeable adhesive that bonds to the mask layer.

A system for providing a force to a desired area on a curved body part of a person includes a dressing assembly shaped and configured to be placed on the desired area of the person, a releaseable circumferential member surrounding the curved body part that holds the dressing assembly against the desired area, a sealing subsystem for providing a fluid seal over the dressing assembly and the person's skin, and a reduced-pressure subsystem for providing a reduced pressure to the dressing assembly. When reduced pressure is supplied, the system generates the force against the desired area on the curved body part.

In general, in an aspect, a barrier includes a water impenetrable membrane having two sides. On one side of the membrane, a continuous strip of adhesive surrounds an adhesive-free central area. The entire extent of the continuous strip of adhesive bears one or more release strips. The membrane is resilient, flexible, and stretchable with an elongation at break in the range of 150% to 1000% (using test ASTM D412).

The present invention pertains to an integrated wound dressing device for treatment of an insertion site of percutaneous and drug delivery devices. The integrated wound dressing device preferably comprises a transparent film layer having a bottom side, a top side and a perimeter. The bottom side is coated with an adhesive impregnated with an antimicrobial agent. The transparent film has a radius cutout between a central opening and the perimeter. A liquid crystal temperature sensitive film with an adhesive placed on the top side of the transparent film layer is preferably near and around the central opening. The dressing also has a layer of double folded release paper below the bottom side of the transparent film layer. The preferred TLCs used are cholesteryl esters with a preferable temperature detection range of 35-40 C. The preferred antimicrobial agent is chlorohexidine gluconate (CHG).

A negative pressure wound dressing for use with breast incisions. The wound dressing includes a drape layer, a manifold layer, a base layer, and a reduced pressure interface. The drape layer has a first surface and a second, wound-facing, surface. The drape layer is substantially impermeable to liquid and substantially permeable to vapor. The manifold layer has a first surface and a second, wound-facing surface. The manifold layer has a perimeter defined by a first convex curved side surface defining a first lobe, a second convex curved side surface defining a second lobe, and a connecting portion between the first lobe and the second lobe. The base layer is configured to: (i) couple the drape layer to the manifold layer, and (ii) the dressing to a patient's tissue. The reduced pressure interface is integrated with the drape layer.

A device for application onto incisions or wounds with a liquid rapidly polymerizable adhesive for forming skin closure systems, comprising a flat porous mesh elongated along a longitudinal axis and having an upper side and an opposing lower or wound facing side and a central portion in immediate vicinity of the axis; further having a plurality of pores and windows in said mesh, said windows substantially larger than said pores and arranged along said longitudinal axis in said central portion; a crosslinking or polymerization accelerator or initiator disposed in or on said mesh; and a pressure sensitive adhesive disposed on at least a portion of the lower surface of said mesh.

A composite wound dressing apparatus promotes healing of a wound via the use of a micropump system housed within or above a wound dressing member. The micropump system includes a miniature pump that applies a subatmospheric pressure to the wound to effectively draw wound fluid or exudate away from the wound bed without the need for a cumbersome external vacuum source. Hence, the wound dressing and micropump system is portable which allows the patient mobility that is unavailable when an external vacuum source is used. The patient does not need to be constrained for any period of time while exudate is being removed from the wound.
